Stabilized zapruder film

Though there's some debate as to its legitimacy,
there's a Quicktime file of the Zapruder film making the rounds, and I'm having a hard time taking my eyes of it. I
certainly don't understand the technology involved, but someone's ostensibly taken the footage – shot on a home
movie camera by an innocent bystander to the JFK assasination, and the key to a conspiracy theory made infamous by
Oliver Stone's JFK – and digitally stabilized and sharpened it. It runs in a loop at the link, and even
slowed down, the meat of the thing goes by so quickly that, if you're anywhere near as morbidly fascinated in this kind
of stuff as I am, you might have a hard time clicking away. Safe for work, but definitely graphic.
